FRANKLIN H. ELWELL, OF C OIL CUP.

Application led November 29, 192?. Seal No.

States, resin.-

-r and Illinois, have invented certain new useful improvements in Oil Cups, ot

invention belongs to that general class of devices known as oil cups and has for one of its objects to provide an oil cup which small continually and oil to the part desired with tational flow, and which may also be ated to feed the oil forcibly whenever desired to do so.

rlhe invention has among production olf a device of the that is simple, convenient, durable.

constantly feed the usual graviactuit is its objects 'the kind described pact, eflicient, dependable, and satisfactory for use wherever found applicable. Many other objects and advantages of the device herein shown and described will to those skilled in the art vention appertains.

to which th be obvious is in# To this end iny invention consists in the novel construction, arrangement and combination oit and more claims.

Aeipertin'es 5) in the plungers 7 transversely n at suitable distances apart and communicating therewith, the bore 8 being terial A, such as ielt, wicking, etc., whereby the oil in the i'eservior may be drawn through the apertures 9 and into the bore t5 by capillary action.

The wick be additionally held iii lace in the bore 8 and prevented from dropping by means ot `a cross pin 9 or its equivalent.

r1`he flange 6 is provided with apertures 10 leading from into the bore 3, mally closed by t spring 12 is posit of the plunger and the flange one end abutting the its other end abutting having the reservoir and opening these openings being norhe plunger 7. A resilient ioned between the head 11 6, said spring head 11 and a washer 13 interposed between the spring and the flange 6, the spring l2 tending to keep the plunger against the top of the cup, whereby the plunger body closes the port 10 and the apertures 10 the apertures 9.

are out ot communication with A cup packing or washer 14 is sebured to the outer end of being preferably on the plunger by Spaced from the the plunger, said washer detachably held in place a removable cap 15.

inner periphery of the casing 1 is a sleeve 16, said sleeve being ot' less length than t nal diameter so as contact with the he casing and of an interouter periphery of the washer 14:, one end of said sleeve havin@` a series of slots 17 therein so that the hilricant may flow through the slots exteriorly 'of the sleeve 16 with the cant remaining` o and freely communicate reservoir, a portion ot' the lubrin both the inside and the outside of thev sleeve.

A removable co the casing in any suitable manner as threading, said ca therein and hav cover plate 20 wh close the hole 19, to lill the reservoir,

ver or cap 18 is secured to 'l o p having a filling hole 19 ng a pivotally mounted ich may be swung so as to or whenever it is desired the hole 19 may be brought into registry with a hole 21 provided in the cove An actuating r through the cap bearing upon the r plate.

od 22 is slidably iiiovabie 1o and cover 20, said. rod cap 15 so as to move the to be in light frictionnl 'lf the actuating rod 22 ,lubricant through the registering apertures 19 and 2l. This lubricant will be absorbed thr ugh the wick A. and will feed constantly through the bores 8 and 3. llllienevei it is `desiredto feed the lubricant forcibly, the

rod22 is pressed inwardly, which movement will actuate both the plunger and the sleeve 1.6 so that the sleeve seats on the end wall 5 of the casing (see dotted lines in Fig. 3), confining the oil between the sleeve and duct. However, since there is only a frictional contact between the washer 'lll and the sleeve 16, the end of the sleeve will remain in Contact with the casing while perinittin the plunger to continue its downward movement. rllie ports l0, normally closed, will then be in communication with the ports Q below the washer 13 and thus will permit the lubricant trapped between the sleeve and the plunger to be forced through the ports l0 into and through the bores 8 and 3 without interrupting the continuity of the capillary oiling action of the plunger. When the rod 22 is released, the spiiiig'?) williretraf-t the rod and the spring 1Q will retract the plu er and move the sleeve into its initial pos as shown in full lines in Fig. 3.

Thus itis seen that the sleeve automatically closes the oil passage between it and the reservoir whenever the plunger is actuated, trapping and confining the oil in the reservoir where pressure may be e:\:'

erted upon it.

lf desired, the actuating rod may be dispensed with, and the cover plate 2() pivoted to the cap 18 by a rivet or the like so@ as to prevent dust and other foieigninaterial from entering the filling hole' 19, while allowingthe cover to be pivoted so that the holes 19 and 2l ai'e brought into registry whenever it is desired to fill the reservoir. is omitted,l then whenever it is desired to forcibly feed the oil through the duct 3, any suitable `instrument may be inserted through the registering openings 19 and 2l and pressed down upon the cap This will actuate the plunger and sleeveY iii the same manner as by the rod 22. lt is quite convenient to use the filling spout of the oil can for the purpose ol. actuating the plunger when the actuating rod 22 is omitted.

Thus it is seen that there is provided an exceedingly simple. cononiical and eflicient oil cup which will permit of using` gravity feeding and yet, whenever it isdesiied to forcibly feed the lubricantA suchma-y be done Without linterriipting the continuity of Vthe gravity feed.
